Bug Description
Description: Ubuntu oneiric (development branch)
Release: 11.10
As of the more recent Google Chrome beta and dev channel releases, Chrome, compiz and Xorg will sporadically use large amounts of CPU up. The problem only manifests itself in compiz and Xorg when it appears in Chrome, so one would suspect it's something Chrome is doing, but maybe compiz could be more resilient.
If it is a Chrome problem, it would be nice if I could squeeze some debugging out of compiz to prove this. Unfortunately, it appears to be non-deterministic, so I can't provide any steps to reproduce.
For reference, here's the output of top:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

Let me know if you need me to provide any more info.

On my machine, this problem seems to be related to chromium app tabs - when the app tab is blinking with notification, the cpu usage by compiz goes to ~ 50 %. Otherwise it is < 10 %.
